In the present invention, the first fabric guide roll A, the second fabric guide roll B, third fabric guide roll C and the 4th fabric guide roll D
Material is preferably the light materials such as carbon fiber or aluminium alloy or glass reinforced plastic.
A kind of preferred course of work as the utility model is as follows: as shown in Figure 2, Figure 4 shows, along 4 traffic direction of fabric according to
Secondary about at least three setting interlocks and is spaced apart from each other the first fabric guide roll A arranged in parallel, the second fabric guide roll B and third fabric guide roll
C, the first fabric guide roll A, the second fabric guide roll B and third fabric guide roll C are preferably with equidistant L1, vertical direction etc. in the horizontal direction
Spacing L2 mode arranges.
Wherein, L1, L2 numerical value can be preset, and numerical value is known；First fabric guide roll A, the second fabric guide roll B
With the radius R of third fabric guide roll CA、RB、RCWith axle journal radius rA、rB、rCGiven value, fabric 4 the first fabric guide roll A with
Length L between third fabric guide roll C is given value, and the angle β between the first fabric guide roll A center of gravity line and its front side fabric 4 is
Know value, the angle α 1, the second fabric guide roll B center of gravity line and its front and back side between the first fabric guide roll A center of gravity line and rear side fabric 4 are knitted
Angle α 4 between angle α 2 between object 4 and α 3 and third fabric guide roll C center of gravity line and its front side fabric 4 is equal and sets
For given value α, fabric area measuring mechanism 2 is preferably that Measuring light screen is mounted in the rack 1 in front of the first fabric guide roll A, this reality
Encoder 6 is preferably installed on the axle journal of the first fabric guide roll A with novel, the encoder 6 follows the first fabric guide roll A to turn together
It is dynamic.
Fabric area S between first fabric guide roll A and third fabric guide roll C is calculated:
For fabric 4 by diagram direction continuous operation, central processing unit receives 6 burst signal of encoder, and is converted to and knits
The mobile distance of object, meanwhile, central processing unit presses set use frequency, acquires the fabric width data of Measuring light screen；When
When the mobile distance of fabric is equal to the length L between the first fabric guide roll A and third fabric guide roll C, central processing unit is in length L
Interior collected fabric width data group makees average calculating operation, obtains fabric mean breadth W, then can be obtained the through W × L calculating
Fabric area S between one fabric guide roll A and third fabric guide roll C.
When the mobile distance of fabric 4 is equal to length L, central processing unit carries out the fabric weight under above-mentioned area S
It calculates, i.e., the grammes per square metre in unit area of the fabric 4 between the first fabric guide roll A and third fabric guide roll C calculates:
Central processing unit receives data of each weighing sensor 3 when fabric is without any fabric guide roll first and deposits
Storage generates weight bias value, by offsetting the self weight of the first, second, third fabric guide roll and bearing holder device, in this way, in fabric
When by the first, second, third fabric guide roll, 3 data of weighing sensor are real-time load of the fabric to each fabric guide roll.
First fabric guide roll A, the second fabric guide roll B and third fabric guide roll C are at by open width fabric dragging and itself revolution
State, in this state, the stress condition of the first fabric guide roll A:
Fs1=(mA× g-T0 × cos β-T1 × cos α) ÷ g --- --- --- --- --- --- --- --- ----(1)
T1= T0+P×μA ×rA÷RA --- --- --- --- --- --- --- --- ----(2)
Wherein, Fs1 is the real-time load of the first fabric guide roll A, mAFor quality+bearing holder device matter of the first fabric guide roll A
Amount, T0 are fabric by the first fabric guide roll A through to input tension, and T1 is fabric by the first fabric guide roll A through to output
Power, g are acceleration of gravity, and P is the pressure of load on bearing, μACoefficient of friction between axle journal and bearing；
Due to μAVery little, P × μA ×rA÷RAIt can be ignored, therefore, T1 ≈ T0=T
Equation (1) simplifies are as follows:
Fs1=(mA× g-T × cos β-T × cos α) ÷ g --- --- --- --- --- --- --- --- ----(3)
Since central processing unit has offset the self weight of the first fabric guide roll A and bearing holder device, equation (3) simplifies
Are as follows:
Fs1=(T × cos β+T × cos α) ÷ g --- --- --- --- --- --- --- --- ----(4)
The stress condition of third fabric guide roll C: it is duplicated completely in the first fabric guide roll A, be can be obtained
Fs3=(T × cos θ+T × cos α) ÷ g --- --- --- --- --- --- --- --- ----(5)
Wherein, Fs3 is the real-time load of third fabric guide roll C, and θ is between third fabric guide roll C center of gravity line and rear side fabric 4
Angle；
The stress condition of second fabric guide roll B:
Fs2=(mB×g+W×g +T1×cosα+ T2×cosα) ÷g
Wherein, Fs2 is the real-time load of the second fabric guide roll B, mBFor quality+bearing holder device matter of the second fabric guide roll B
Amount, W are the fabric quality that fabric 4 reaches third fabric guide roll C by the second fabric guide roll B, and T1 is fabric by the second fabric guide roll B's
Through to input tension, T2 fabric is by the second fabric guide roll B through to output tension；
T2= T1+P×μB ×rB÷RB, due to μBVery little, P × μB ×rB÷RBIt can be ignored, therefore, T1 ≈ T2
=T,
According to the first fabric guide roll A simplified pinciple, Fs2 can simplify are as follows:
Fs2=(W × g+2 × T × cos α) ÷ g --- --- --- --- --- --- --- --- ----(6)
Fs2-Fs1=W+2 × T × cos α ÷ g-(T × cos β+T × cos α) ÷ g ----(7)

In equation (7), as β=α, ︱ Fs2 ︱-︱ Fs1 ︱=W --- --- --- --- (9)
Grammes per square metre of the fabric 4 in the unit area between the first fabric guide roll A and third fabric guide roll C:
ρ=(︱ Fs2 ︱-︱ Fs1 ︱)/S.
Similarly, in equation (8), as θ=α, ︱ Fs2 ︱-︱ Fs3 ︱=W
Grammes per square metre of the fabric 4 in the unit area between the first fabric guide roll A and third fabric guide roll C:
ρ=(︱ Fs2 ︱-︱ Fs3 ︱)/S.
The utility model can accurately measure the real-time grammes per square metre of fabric, and easy to operate, achieve good by trying out
Effect.
